EDDIE EDMUNDS, OF SAN ANTONIO, TEXAS, ASSIGNOR TO STEVE M. FOSTER, OF SAME PLACE, AND BEEVER & HINDES, OF PEARSALL, TEXAS.

CACTUS-BURNER.

SPECIFICATION forming part of Letters Patent No. 613,798, dated November 8, 1898.

Application filed February 21, 1898. Serial No. 671,150. (No model.)

To all whom it may concern.-

Be it known that I, EDDIE EnMUNDs, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Oacins-Burner, of which the following is a specification.

This invention relates to an apparatus for removing the thorns from cactus or pricklypears or like fleshy and succulent growths provided with spines, thereby adapting the same to be fed to stock and obviating the danger which would be incurred by feeding such growths to the stock in a natural or normal condition.

The purpose of the invention is the provision of an apparatus which will be light, portable, safe, and capable of projecting a flame for singeing and removing the thorny projections.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which-- Figure 1 is a perspective View of the apparatus. Fig. 2 is a sectional detail of the burner and generator. Fig. 3 is a perspective view of a modified form of burner. Fig. 4 is a detail View showing the supply-pipe provided with a wire filling or cable and the receiving end of the main supply-pipe having a plug with a minute aperture.

Corresponding and like parts are referred to in the following description and indicated in the views of the drawings by the same reference characters.

The tank or reservoir 1 is of convenient size, so as to be readily portable, and is provided at its sides with keepers 2 for attachment therewith of the straps 3, by means of which the reservoir may be secured to the person. A strap 4 is applied-to the upper portion of the reservoir and is intended to pass over the shoulder of the person, thereby supplementing the action of the straps 3 in properly positioning and supporting the reservoir or tank when in place and ready for 5 5 use. A hollow plug 5 is fitted to the upper end of the tank and has one end of a flexible tube 6 secured thereto, the opposite end of said tube being provided with a bulb 7 or other means for supplying air to the upper portion of the reservoir under pressure, so as to expel the hydrocarbon therefrom when the apparatus is in service. A short pipe 8 has connection with the lower portion of the res ervoir and is provided at its outer end with a valve 9 of the globe variety. A second pipe 11 connects at its inner end with the outer end of the valve-casing 9, and a flexible tube 12 is fitted to the outer end of the pipe 11.

A delivery-pipe 10 is fitted to the outer end of the tube 12 and has a T-coupling 20 at its outer end, the branches of which are fitted to parallel pipes 18 and 19, which form extensions of coils 16 and 17, respectively. These coils 16 and 17 are concentrically disposed and are interlocked at their inner ends to prevent relative displacement. The terminal portion of the pipe forming the inner coil' 16 is extended axially with respect to the coil and constitutes a burner-tube 15 for general 8o An outlet-opening 22 is formed in the in- 90 ner side of the burner-tube 21 in axial aline ment with the coils or helical generators, so as to project a flame through the space circumscribed by the inner coil or generator, so

as to heat the same sufficiently to convert 5 the hydrocarbon into vapor to be consumed when the apparatus is in active operation.

In order to prevent the too rapid flow of the hydrocarbon to the burner, the deliverypipe 10 and the pipe 18 are filled with a cap- Ice illary or absorbent material, through which the liquid fuel seeps on its way to be vapo- The coils 16 and 17 constitute generarized and support the flame. The liquid fuel may be gasolene, kerosene, naphtha, or any volatile hydrocarbon which is capable of being readily converted into vapor in the pres ence of heat. When the apparatus is in active operation, the hydrocarbon is caused to feed positively to the burner by subjecting it to atmospheric pressure, the latter being securedby the bulb or other air-compressin g device connected therewith. The tank or reservoir is attached to the person by means of the straps 3 and 4, thereby leaving the hands free for manipulating the burner, so that the flame can be directed upon the cactus or other growth from which the thorns or spines are to be removed by a singeing process.

As shown in Fig. 3, the tank or reservoir occupies a horizontal position instead of be ing upright, as indicated in Fig. 1, and is provided in its top side with a screw plug or cap 23, by means of which the hydrocarbon is supplied thereto. The flexible tube of the air-pump has connection with a tubular stem 24, located at the upper side of the tank. The supporting means dis a cord or rope and is secured at its ends to the ends of the tank by means of cables 2, applied thereto. The pipe 8, with its connections, is applied to an end of the tank, close to the bottom side thereof. This form of the apparatus is more con- The flow of the oil is further retarded by placing a wire cable 26 within the pipes 10, 1S, and 19, the oil passing slowly through the interstitial spaces between the strands comprising said cable. The wire cable, being a good conductor of heat, assists in vaporizing the oil and in providing an extended heating-surface.

Having thus described the invention, What is claimed, and desired to be secured by Letters Patent, is-

1. In an apparatus of the class described, the combination with a reservoir or tank, of the inner and outer concentric coils connected with the tank or reservoir at one end and provided at their other ends with burners, one of the burners being arranged for heating the coils and the other being extended therefrom and disposed for general heating purposes, substantially as described.

2. In an apparatus of the class described, the combination of a tank, a delivery-pipe connected with the tank, parallel pipes connected at their inner ends with the deliverypipe, and the concentric helical generators connected with the outer ends of the parallel pipes and having extended terminals provided with burners, one of the burners being arranged to heat the coils and the other being disposed for general heating purposes, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

EDDIE EDMUNDS.
